WINDOW-SCREEN.

SPECIFICATION formingpart of Letters Patent No. 726,851, dated May 5,1903. Application filed December 20, 1901. Serial No. 86,629. (Nomodel.)

To aZZ whom it may concern.-

Be it known that I,.JAcoB BIRMELIN, a citizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio, haveinvented certain new and useful Improvements in Window-Screens; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

Myinvention relates to and its object is to 5 provide a window-screenwhich shall always be in place and ready for use and which when not inuse shall be concealed, housed, and protected from the weather. I attainthese objects by means of the devices and arrangement of partshereinafter described and shown, and illustrated in the accompanyingdrawings, in Which--- Figure 1 is a side elevation of my device seenfrom a houseinterior, showing the window raised and the screen inoperative position; Fig. 2, a central sectional edge view of the samewith the screen concealed and with the hook hereinafter referred toengaged with the screen ready to lift the screen; and Fig. 3 is thesame, showingthe sash raised and the hook and screen out of engagementwith each other.

Like numerals of reference indicate like parts throughout the drawings.

In the drawings, 1 is a window-casing in which slides a window-sash 2.Through the Window-sill 3 is a narrow vertical opening 4 of the samewidth as and immediately beneath the bottom rail of the window-sash. Inthe wall beneath the window-sill is a pocket or chamber 5, whichordinarily extends to the floor of the room.

6 is a window-screen composed of wire-cloth mounted at its margins inthe fold of doubled sheet-metal strips 7. If preferred, the wireclothmay be in two equal pieces, the vertical meeting edges of which may alsobemounted in the folds of like sheet-metal strips 8. The

vertical outer margins of the screen may when raised rest snugly againstthe sides of the window-frame, or, if preferred, they may slide ingrooves formed in the side of the windowscreen concealed in the pocket,

frame. When the screen is lowered to its lowest point, it passes throughand is suspended from the window-sill in the pocket or chamber 5 bynarrow horizontal flanges 8 011 the top of the metal screen-frame.

The lower rail of the sash is grooved along its bottom, as at-9, toreceive the top of the screen. The lower railof the sash, on its innervertical side midway of its length, has a mortise leading into thegroove 9. [A plate 10, secured to the sash, covers the mortise and hason its inner sidelugs 10",, in which is pivoted a hook 11. This hook atbottom has a catch which is adapted to engage an opening 12 in the topofthe frame of the screen. The hook at top curves outwardly, forming aconvenient finger-piece, by means of which the sash'may be raised andlowered.

The operation of my device is as follows: When the window-sash islowered and when no screen is needed, the screen hangs suspended fromthe top margins of the opening 4 by the narrow horizontal flanges 8formed on top of the frame of the screen. When it becomes necessary toraise the window, when no screen is required, the operator presses thefinger-piece ofthe hook 11 inwardly, thus disengaging the lowerend ofthe hook from the screen, and pulls upwardly "on the fingerpiece, thuslifting the sash and leaving the When it is desired to raise the windowand to close the opening with the screen, the finger-piece of the hookis drawn outwardly. Now the screen is engaged by the hook, and thescreen may be lifted with the sash. When the sash and the screen areraised, the screen may at any time be lowered or dropped by simplypressing inwardly on' the finger-piece, thus disengaging the book fromthe screen. It will be seen that the screen is always in place ready foruse, that when not in use the screen is housed and stored away from theweather, and that no matter how high the window-sash is raised thescreen exactly fills the opening.

Having described my invention, whatv I claim, and desire to secure byLetters Patent, 1

A window-frame, a pocket beneath the frame, a sill for the window-framehaving a slot which leads into said pocket, a sash movable in saidframe, a screen adapted to slide :0 and lowered the arrangement beingsuch that outward pressure on the finger-piece will engage the hook withthe screen and such that inward pressure on the finger-piece willdisengage the hook from the screen.

In testimony whereof I affix my signature :5

in presence of two witnesses.
